1/ b all whom it may concern:

Be it known that I, VILLIAM S. HAMM, a citizen of the United States, and resident of Hubbard lVoods, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Signal-Lamps, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to lamps having a sliding door; its object being to provide a weather guard for excluding drafts at the sides of the door; and it consists in the novel features of the lamp as hereinafter described, and as illustrated in the accompanying drawings, in which Figure 1 is a detail perspective of the lamp, some portions being broken away; Fig. 2 is a detail plan section through the door and the frame upon which it is mounted; and Fig. 3 is a perspective of the weather guard strip detached.

The body of the lamp is shown at 10, and its sliding door at 11, the door having its side edges folded inward, as shown at 12, to engage a laterally projecting lip 13 of an outstanding flange 14 of the body flanking the door opening. Such connection being formed at both sides of the door, the latter will slide vertically upon the ways thus formed.

In lamps of this character it is important that drafts should be excluded in order that the flame may not be interfered with. For this purpose a U-shaped sheet-metal strip 15 is inserted bet-ween the body of the lamp and the inwardly folded lip 12 of the door, one leaf of the strip being secured by solder, or other means, to the lamp body at 16, the other lip 17 of the strip bearing by its edge against the face of the lip 12. The strip 15 possesses suflicient elasticity to insure a tight joint with the lip 12, and as the edge 17 of the strip is directed outwardly there is presented no flat or broad surface against which the wind can press and effect an entrance; on the contrary, as the inner face of the'bow of the strip is presented to the wind the pressure tends to more tightly close the joint. The elastic pressure of the weather guard against the lip of the door is not sufficient to prevent the free sliding of the door in opening and closing.

I claim as my invention 1. In a lamp, in combination, a body having a door opening with outstanding flanges at its sides, a'door having inturned lips at its sides slidingly engaging the flanges, and a sheet metal weather guard secured to the body and having an outwardly directed edge bearing against the inner face of one of the inturnecl lips.

2. In a lamp, in combination, a body having a door opening with an outstanding flange at its side, a door having an inturned lip slidingly engaging the flange, and a sheet metal weather guard secured to the body and having an outwardly directed edge bearing-against the inner face of the inturned lip.

3. In a lamp, in combination, a body having a door opening, an outstanding flange at the side of the opening and having a backwardly turned leaf, a door having an inturned lip slidingly engaging the backwardly turned leaf of the flange, and a bowed spring plate inclosed within the backwardly turned leaf and having one leaf secured to the body and the other leaf bearing against the lip of the door.

4. In a lamp, in combination, a body having a door opening with outstanding flanges at its sides, a door having inturned lips at its sides slidingly engaging the flanges, a spring metal weather guard reacting between the body and one of the lips of the door and being secured to one of such members and having its free edge directed outwardly and bearing against the other of said members.
